Exploring the possibilities with the banjo fitting oil mod, I find that I can buy a 10 X 1.25MM bolt 40MM long, hopefully with about an inch of shoulder. By drilling a hole through the head of a reasonable size, since there are no threads there, I can cross-drill ports in both levels and the 2 stacked banjos will communicate well and there is no passage to the original oil source. Then a doped setscrew to plug the top of the hole. Well, whaddya think? opinions, please
